Just simple vector piano keys. I wasn't able to find any at dA when I needed them so figured I would save someone the time and upload these.
Feel free to use these as you wish, but let me know how they are used. It's always fun to see other outcomes.
<EDIT>Sorry for such a small preview image. Silly 150x150 rule... Dimension of the unedited workable file is actually 507x54 pixels.</EDIT>
